Application filed August 26, 1914-.- Serial No. 858,688.

To all whom it may concern:

Be it known that we, CLARENCE A. PHELPS and JOHN C. GOLLER, citizens of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Fluid- Fuel Filters, of which the following is a specification.

This invention relates to improvements in filters and to such as are particularly adapt" ed for the straining of the fuel of internal combustion engines.

The primary object in view is the removal of all aqueous and foreign substances from the fluid fuel, and a further object is the easy disposal of such removed foreign'substances.

With these and further objects in view, as will in part hereinafter become apparent, and in part be stated, the invention comprises certain novel constructions, combinations, and arrangements of parts as subse quently specified and claimed.

In the accompanying drawing: Figure 1 is a longitudinal, vertical, central section of an apparatus embodying the features of the present invention. Fig. 2 is a transverse section therethrough taken on the plane indi cated by the line 2-2 of Fig. 1 and looking in the direction of the arrow. Fig. 3 is a view similar to Fig. 1 of the central section and one terminal section, the parts being shown in the position assumed while being supported.

Referring to the drawings by numerals, 1 indicates a tubular central section or chamber having at each end an annular shoulder 2 and an internal thread extending from the shoulder to the respective end of the section, said thread being engaged by a tubular terminal section or chamber 3, there being a terminal section at each end of the central section. A sheet offiltering material preferably chamois skin 4 closes each end portion of section 1 and extends about the shoulder 2 and is engaged and retained in place by an annulus 5, preferably of metal which annulus is engaged by the inner end of the respective terminal section 3 and pressed thereby into clamping engagement with the chamois skin 4, clamping the same against the respective annular shoulder 2. Each annulus 5 may be of any appropriate material, and preferably consists of a metal ring, and each annulus is provided with an axially extended finger 6 formed integral parts are assembled as indicated in Fig. 1

extends past the respective flange 8 adistance approximately equal to the distance the respective section 3 is threaded into section 1 so that when the terminal section is disconnected fromthe central section by being unscrewed therefrom, the hook 7 will engage the flange 8 just as the terminal section becomes disconnected from the central section so that the terminal section can be moved laterally or pivotally to the position indicated in Fig. 3 and such movement will cause the upper portion of the ring or annulus 5 to be swung outwardly. Thus the ring is easily loosened and readily removed for enabling removal of the filter 4 for cleansing or renewal.

The intake terminal section 3, that is the section first approached by the gasolene or other fluid fuel, is provided with a. drain cock 9 and the central section is provided with a similar drain cook 10, each of the drain cocks being arranged at the lowermost point in the respective section so that water, grit or other foreign substances collecting at the lower portions of the respective sections can be easily drained therefrom.

The operation of the structure isobvious and consistsin the supplying of fuel through a pipe 11 into the intake terminal section 3 through the outer closed end thereof from any appropriate source as from the tank of an ordinary automobile. The inflowing fuel penetrates the first filter sheet 4 and passing through the central chamber penetrates the second filter sheet 1 and passes out through the discharge terminal section3through a discharge pipe 12 which communicates through the outer closed end of the last-named section 3, said pipe extending to any appropriate point of consumption as, for instance, the carbureter of an ordinary automobile engine.

Aqueous and other foreign substances retarded by the filter 4 are precipitated from the column of fluid fuel always standing in the several sections during use and finding their way to the drain cocks 9 and 10 may be readily removed therethrough, It is observed that the outlet pipe 12 is on a plane at the uppermost portion of the section, and,

therefore, in use the several sections are maintained substantially filled with fluid fuel for effecting discharge through pipe 12, so that ample opportunit is afforded for the maintenance of quiet bodies of fluid in which the foreign substances may be precipitated substantially without interruption such as that incident to agitation as would small rapidly movingseparated.

2. In a fluid fuel filter, the combination of an annular chamber, a second annular chamber threaded into the first, a sheet of filterin material disposed between the inner en of the second annular chamber and the engaged portion of the first annular chamber, a retaining annulus disposed between said sheet and the inner end of the second chamber, a finger extending axially from the annulus into the second mentioned chamber, and means in the second mentioned chamber engaging the finger for removing the annulus when the second-mentioned chamber is detached from the first.

3. In a fluid fuel filter, the combination of an annular chamber, a second annular chamber threaded into the first, a filter sheet dividing the two chambers and having its peripheral portions lying between the inner end of the second chamber and the engaged portion of the first, an annulus between the inner end of the second chamber and the filter sheet, a finger extending axially from the annulus into the second-mentioned chamber and having a hook at its free end portion, and. an external annular flange in the,

second-mentioned chamber adapted to engage the hook of the finger when the secondmentioned chamber is detached from the first.

In testimony whereof we aiiix our signatures in presence of two witnesses.
